Numerical settings for the two resolution tiers in this work.

Resolution Tier	N_active	N_u	$N_{C_{ψ}}$ $Mathematical equation: ${N_{{C_\psi }}}$$	$N_{C_{α}}$ $Mathematical equation: ${N_{{C_\alpha }}}$$	N_fp	$N_{E_{0}}$ $Mathematical equation: ${N_{{E_0}}}$$
std-resolution	128 × 128	256	512	512	192	128
high-resolution	256 × 256	256	512	512	192	128

Notes. Only the count of active surface patch N_active varies across tiers; all other precision parameters (the number of discretized compactness in lensing table N_u, the number of discretized cos ψ in lensing table $N_{C_{ψ}}$ $Mathematical equation: ${N_{{C_\psi }}}$$ , the number of discretized cos α in lensing table $N_{C_{α}}$ $Mathematical equation: ${N_{{C_\alpha }}}$$ , the number of fine phase N_fp, the number of down-sampling observed photon energy grid $N_{E_{0}}$ $Mathematical equation: ${N_{{E_0}}}$$ ) are held fixed.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
